White mushrooms are usually safe to consume for about a week when stored in the refrigerator. However, they can go bad and exhibit signs of spoilage, such as a slimy texture, dark spots, discoloration, and an unpleasant smell. Consuming spoiled mushrooms can lead to foodborne illnesses, so it is important to inspect them for any signs of spoilage before consumption and practice proper food handling and storage techniques to maintain freshness and prevent bacterial growth.

White mushrooms should be stored in the fridge and eaten within 4 to 7 days
White mushrooms are versatile and delicious, but they don't last long. To keep them fresh, store them in the fridge and eat them within 4 to 7 days.
Whole white mushrooms should be stored in the fridge and will last for up to 7 days. They should be smooth, plump, firm, and evenly coloured. White mushrooms are usually safe for about a week in your fridge. However, some sources advise eating them within 4 days, as they can spoil quickly.
Sliced mushrooms don't last as long as whole mushrooms because they have a larger surface area exposed to the air. They can spoil twice as fast as whole mushrooms, so buy them whole and slice them just before use. If you do buy sliced mushrooms, try to use them the same day.
To keep your white mushrooms fresh for longer, transfer them from their original container to a brown paper bag and place them in the fridge. The paper bag will help to keep moisture at bay and prevent spoilage. You can also wrap the mushrooms in a paper towel before placing them in the bag to absorb any excess moisture. Avoid storing mushrooms in plastic bags or sealed containers, as the lack of airflow will speed up spoilage.
Signs that your white mushrooms are spoiling include a slimy texture, discolouration, and an unpleasant smell. Mushrooms that have started to wrinkle are getting old and dehydrated. If they are very wrinkled and shrivelled, they are too far gone and should not be eaten.

They spoil faster when sliced, so buy whole mushrooms and slice before use
White mushrooms, like other varieties, can spoil and go bad. They have a limited shelf life and can show signs of spoilage quickly. It is important to know how to identify spoiled mushrooms to avoid getting sick.
Fresh mushrooms should be plump, firm, smooth, evenly coloured, and dry, with a light earthy smell. Bad mushrooms are softer, sticky, slimy, shrivelled, discoloured, and may smell unpleasant, like ammonia or rotten fish. They may also develop bruises, brown spots, or mould.
To ensure the freshness of white mushrooms, it is recommended to buy them whole and slice them just before use. Sliced mushrooms have a shorter shelf life than whole mushrooms because they have a larger surface area exposed to the surrounding conditions. This increased surface area allows more moisture to escape, leading to faster dehydration and spoilage.
When buying white mushrooms, it is best to avoid pre-packaged containers and opt for loose mushrooms so you can inspect their quality. Choose mushrooms that feel dry and firm to the touch, with a smooth outer appearance. If they appear dirty, use a dry paper towel or cloth to gently wipe them clean before storing.
Proper storage is crucial to prolonging the life of white mushrooms. They should be stored in the refrigerator, preferably in a paper bag or wrapped in a paper towel, rather than in plastic bags or sealed containers, as these can trap moisture and accelerate spoilage. With proper storage, whole white mushrooms can last approximately four to seven days in the refrigerator.

Signs of spoilage include slimy texture, discolouration, bruises, and a fishy or sour smell
When it comes to white mushrooms, there are several signs of spoilage to look out for. Firstly, a slimy texture is a clear indication that mushrooms are beginning to rot and spoil. This is often the result of incorrect storage or keeping them in the fridge for too long. While some sources suggest that mushrooms with a slimy texture can still be cooked and consumed, others advise against it, especially if there are other signs of spoilage present.
Discolouration is another sign that white mushrooms are going bad. Fresh mushrooms should appear plump, firm, and evenly coloured. As they start to spoil, they may develop bruises, brown spots, or dark spots, indicating that they are past their prime and should not be eaten. Being exposed to air for too long can cause mushrooms to oxidize and discolour.
In addition to visual cues, spoilage can also be identified through smell and texture. Fresh mushrooms should have a pleasant, slightly sweet, and earthy aroma. If they start to smell fishy or sour, it indicates that they have gone bad and should be discarded. Mushrooms that have become soggy, soft, or floppy have likely been stored for too long and are no longer edible.
It is important to note that sliced mushrooms spoil faster than whole mushrooms due to their larger surface area. Proper storage is crucial to prolonging the shelf life of white mushrooms. They should be stored in a paper towel-lined paper bag in the refrigerator and used within four to seven days to prevent spoilage.

Avoid storing in plastic bags or sealed containers, as this causes rapid spoilage
Proper storage is key to keeping your white mushrooms fresh for longer. When stored correctly, whole, raw mushrooms can last for approximately four to seven days in the refrigerator.
However, it is important to avoid storing mushrooms in plastic bags or sealed containers. The lack of airflow in these storage methods will cause rapid spoilage. Mushrooms have a high water content, and when fresh, they should be smooth, plump, and firm. They also have a light earthy smell.
Instead of plastic bags or sealed containers, transfer your mushrooms from their original packaging to a brown paper bag. Place the bag in the fridge. The paper bag will help to keep any moisture at bay and prevent the mushrooms from becoming slimy. You can also line the paper bag with a paper towel to absorb any excess moisture.
If you are storing sliced mushrooms, their shelf life will be shorter, typically around three to five days. Sliced mushrooms have a greater surface area exposed to the air, which can cause them to spoil more quickly. To prolong their freshness, try to buy whole mushrooms and slice them just before use.

Keep mushrooms away from raw meat and strong-smelling foods to prevent cross-contamination and odour absorption
Fresh mushrooms are dry, firm, smooth, and have a pleasant earthy smell. They don't have a long shelf life and can show signs of spoilage quickly, so it's important to store them properly.
To prevent cross-contamination and odour absorption, it is important to keep mushrooms away from raw meat and strong-smelling foods. Mushrooms are susceptible to absorbing bacteria from their surroundings, so they should be stored separately from raw meat, eggs, and seafood. This is especially important if you plan on consuming the mushrooms raw. During food preparation, it is recommended to use separate cutting boards and knives for raw meat and mushrooms to further reduce the risk of cross-contamination.
Additionally, mushrooms have a high capacity for absorbing odours, so storing them away from strong-smelling foods will help prevent them from taking on undesirable aromas. Mushrooms should be wrapped in a paper towel and placed in a brown paper bag or their original packaging in the refrigerator. This will help to maintain their freshness and minimize odour absorption.
It is also worth noting that sliced mushrooms have a shorter shelf life than whole mushrooms due to their increased surface area. Therefore, it is advisable to buy whole mushrooms and slice them just before use, or purchase sliced mushrooms on the day of use. By following these storage and handling practices, you can help maintain the quality and safety of your mushrooms while preventing cross-contamination and odour absorption.
To identify if mushrooms have gone bad, look for signs such as a slimy texture, dark spots, discolouration, and a fishy or sour smell. If any of these indicators are present, it is best to discard the mushrooms to avoid potential health risks.
